Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We can use the usable rules and reduction pair processor [15] with the Ce-compatible extension of the polynomial order that maps every function symbol to the sum of its argument. Then, we can delete all non-usable rules [17] from R.

Q DP problem:
The TRS P consists of the following rules:

ISNEPAL(ok(X)) → ISNEPAL(X)

R is empty.
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By using the subterm criterion [20] together with the size-change analysis [32] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

ISNEPAL(ok(X)) → ISNEPAL(X)
The graph contains the following edges 1 > 1

The TRS P consists of the following rules:

U81¹(ok(X1), ok(X2)) → U81¹(X1, X2)
U81¹(mark(X1), X2) → U81¹(X1, X2)

From the DPs we obtained the following set of size-change graphs:

U81¹(mark(X1), X2) → U81¹(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2
U81¹(ok(X1), ok(X2)) → U81¹(X1, X2)
The graph contains the following edges 1 > 1, 2 > 2

Q DP problem:
The TRS P consists of the following rules:

U73¹(ok(X1), ok(X2)) → U73¹(X1, X2)
U73¹(mark(X1), X2) → U73¹(X1, X2)

From the DPs we obtained the following set of size-change graphs:

U73¹(ok(X1), ok(X2)) → U73¹(X1, X2)
The graph contains the following edges 1 > 1, 2 > 2
U73¹(mark(X1), X2) → U73¹(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2

Q DP problem:
The TRS P consists of the following rules:

U72¹(ok(X1), ok(X2)) → U72¹(X1, X2)
U72¹(mark(X1), X2) → U72¹(X1, X2)

From the DPs we obtained the following set of size-change graphs:

U72¹(ok(X1), ok(X2)) → U72¹(X1, X2)
The graph contains the following edges 1 > 1, 2 > 2
U72¹(mark(X1), X2) → U72¹(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2

Q DP problem:
The TRS P consists of the following rules:

U71¹(mark(X1), X2, X3) → U71¹(X1, X2, X3)
U71¹(ok(X1), ok(X2), ok(X3)) → U71¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U71¹(mark(X1), X2, X3) → U71¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3
U71¹(ok(X1), ok(X2), ok(X3)) → U71¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3

Q DP problem:
The TRS P consists of the following rules:

U62¹(mark(X1), X2) → U62¹(X1, X2)
U62¹(ok(X1), ok(X2)) → U62¹(X1, X2)

From the DPs we obtained the following set of size-change graphs:

U62¹(mark(X1), X2) → U62¹(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2
U62¹(ok(X1), ok(X2)) → U62¹(X1, X2)
The graph contains the following edges 1 > 1, 2 > 2

Q DP problem:
The TRS P consists of the following rules:

U61¹(mark(X1), X2) → U61¹(X1, X2)
U61¹(ok(X1), ok(X2)) → U61¹(X1, X2)

From the DPs we obtained the following set of size-change graphs:

U61¹(mark(X1), X2) → U61¹(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2
U61¹(ok(X1), ok(X2)) → U61¹(X1, X2)
The graph contains the following edges 1 > 1, 2 > 2

Q DP problem:
The TRS P consists of the following rules:

U55¹(ok(X1), ok(X2)) → U55¹(X1, X2)
U55¹(mark(X1), X2) → U55¹(X1, X2)

From the DPs we obtained the following set of size-change graphs:

U55¹(ok(X1), ok(X2)) → U55¹(X1, X2)
The graph contains the following edges 1 > 1, 2 > 2
U55¹(mark(X1), X2) → U55¹(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2

Q DP problem:
The TRS P consists of the following rules:

U54¹(mark(X1), X2, X3) → U54¹(X1, X2, X3)
U54¹(ok(X1), ok(X2), ok(X3)) → U54¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U54¹(mark(X1), X2, X3) → U54¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3
U54¹(ok(X1), ok(X2), ok(X3)) → U54¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3

Q DP problem:
The TRS P consists of the following rules:

U53¹(ok(X1), ok(X2), ok(X3)) → U53¹(X1, X2, X3)
U53¹(mark(X1), X2, X3) → U53¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U53¹(ok(X1), ok(X2), ok(X3)) → U53¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3
U53¹(mark(X1), X2, X3) → U53¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3

Q DP problem:
The TRS P consists of the following rules:

U52¹(mark(X1), X2, X3) → U52¹(X1, X2, X3)
U52¹(ok(X1), ok(X2), ok(X3)) → U52¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U52¹(mark(X1), X2, X3) → U52¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3
U52¹(ok(X1), ok(X2), ok(X3)) → U52¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3

Q DP problem:
The TRS P consists of the following rules:

U51¹(mark(X1), X2, X3) → U51¹(X1, X2, X3)
U51¹(ok(X1), ok(X2), ok(X3)) → U51¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U51¹(mark(X1), X2, X3) → U51¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3
U51¹(ok(X1), ok(X2), ok(X3)) → U51¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3

Q DP problem:
The TRS P consists of the following rules:

U45¹(ok(X1), ok(X2)) → U45¹(X1, X2)
U45¹(mark(X1), X2) → U45¹(X1, X2)

From the DPs we obtained the following set of size-change graphs:

U45¹(ok(X1), ok(X2)) → U45¹(X1, X2)
The graph contains the following edges 1 > 1, 2 > 2
U45¹(mark(X1), X2) → U45¹(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2

Q DP problem:
The TRS P consists of the following rules:

U44¹(mark(X1), X2, X3) → U44¹(X1, X2, X3)
U44¹(ok(X1), ok(X2), ok(X3)) → U44¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U44¹(mark(X1), X2, X3) → U44¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3
U44¹(ok(X1), ok(X2), ok(X3)) → U44¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3

Q DP problem:
The TRS P consists of the following rules:

U43¹(mark(X1), X2, X3) → U43¹(X1, X2, X3)
U43¹(ok(X1), ok(X2), ok(X3)) → U43¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U43¹(mark(X1), X2, X3) → U43¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3
U43¹(ok(X1), ok(X2), ok(X3)) → U43¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3

Q DP problem:
The TRS P consists of the following rules:

U42¹(mark(X1), X2, X3) → U42¹(X1, X2, X3)
U42¹(ok(X1), ok(X2), ok(X3)) → U42¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U42¹(mark(X1), X2, X3) → U42¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3
U42¹(ok(X1), ok(X2), ok(X3)) → U42¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3

Q DP problem:
The TRS P consists of the following rules:

U41¹(ok(X1), ok(X2), ok(X3)) → U41¹(X1, X2, X3)
U41¹(mark(X1), X2, X3) → U41¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U41¹(ok(X1), ok(X2), ok(X3)) → U41¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3
U41¹(mark(X1), X2, X3) → U41¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3

Q DP problem:
The TRS P consists of the following rules:

U24¹(mark(X1), X2, X3) → U24¹(X1, X2, X3)
U24¹(ok(X1), ok(X2), ok(X3)) → U24¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U24¹(mark(X1), X2, X3) → U24¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3
U24¹(ok(X1), ok(X2), ok(X3)) → U24¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3

Q DP problem:
The TRS P consists of the following rules:

U23¹(ok(X1), ok(X2), ok(X3)) → U23¹(X1, X2, X3)
U23¹(mark(X1), X2, X3) → U23¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U23¹(ok(X1), ok(X2), ok(X3)) → U23¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3
U23¹(mark(X1), X2, X3) → U23¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3

Q DP problem:
The TRS P consists of the following rules:

U22¹(mark(X1), X2, X3) → U22¹(X1, X2, X3)
U22¹(ok(X1), ok(X2), ok(X3)) → U22¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U22¹(mark(X1), X2, X3) → U22¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3
U22¹(ok(X1), ok(X2), ok(X3)) → U22¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3

Q DP problem:
The TRS P consists of the following rules:

U21¹(ok(X1), ok(X2), ok(X3)) → U21¹(X1, X2, X3)
U21¹(mark(X1), X2, X3) → U21¹(X1, X2, X3)

From the DPs we obtained the following set of size-change graphs:

U21¹(ok(X1), ok(X2), ok(X3)) → U21¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 > 2, 3 > 3
U21¹(mark(X1), X2, X3) → U21¹(X1, X2, X3)
The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3

Q DP problem:
The TRS P consists of the following rules:

U11¹(ok(X1), ok(X2)) → U11¹(X1, X2)
U11¹(mark(X1), X2) → U11¹(X1, X2)

From the DPs we obtained the following set of size-change graphs:

U11¹(mark(X1), X2) → U11¹(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2
U11¹(ok(X1), ok(X2)) → U11¹(X1, X2)
The graph contains the following edges 1 > 1, 2 > 2

Q DP problem:
The TRS P consists of the following rules:

__¹(ok(X1), ok(X2)) → __¹(X1, X2)
__¹(X1, mark(X2)) → __¹(X1, X2)
__¹(mark(X1), X2) → __¹(X1, X2)

From the DPs we obtained the following set of size-change graphs:

__¹(ok(X1), ok(X2)) → __¹(X1, X2)
The graph contains the following edges 1 > 1, 2 > 2
__¹(X1, mark(X2)) → __¹(X1, X2)
The graph contains the following edges 1 >= 1, 2 > 2
__¹(mark(X1), X2) → __¹(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By using the usable rules with reduction pair processor [15] with a polynomial ordering [25], all dependency pairs and the corresponding usable rules [17] can be oriented non-strictly. All non-usable rules are removed, and those dependency pairs and usable rules that have been oriented strictly or contain non-usable symbols in their left-hand side are removed as well.

No dependency pairs are removed.

No rules are removed from R.
